A Japanese toy maker declares that they have ...

A Japanese toy maker declares that they have developed a gadget that translates dog barks into human language and plans to begin selling the gadget——under the name of Bowlingual——in U. S. pet stores and gift shops this summer.

Tokyo-based Takara Co. Ltd. says about 300, 000 of the dog translator gadgets have been sold since it was on sale in Japan late last year. It is forecasting far bigger sales once an English language translation for dogs comes to America in August. The United States is home to about 67 million dogs, more than six times the number in Japan.

"We know that the Americans love their dogs so much, so we don't think they will mind spending $ 120 on this product, " the Takara marketing manager said during an interview at a recent pet products conference in Atlanta.

Regarded as one of the coolest inventions of 2002 by Time magazine, Bowlingual is made up of a 3 - inch long wireless microphone that is fastened to a dog collar and sends out sounds to a small console (控制台) that is connected to a database (数据库). The console divides each bark into six emotional types——happiness, sadness, disappointment, anger, threat and desire——and shows common phrases, such as "You're ticking me off," that fit the dog's emotional state.

Takara says it has spent millions of dollars developing the gadget in cooperation（合作）with famous sound experts and animal behaviorists.

One thing that does appear certain is that the markets for animal translation products will likely remain a dog's world since Takara has no plans to develop a similar gadget for cats. "They are too unpredictable (反复无常) , " the marketing manager said.

1.This passage mainly tells us that Bowlingual ___________.

A．was invented in Japan 　　　            B．has developed quickly

C．will be sold in America                   D．sells well for its price

2.The underlined word "they" in the last paragraph refers to ___________.

A．markets           B．products          C．plans             D．cats

3.From the passage, we can see that Takara Co. Ltd. is ___________ the sale of its new product.

There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.

In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly(严格地) determined, boys pattern their play after the activities of their fathers and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.

What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality(普遍性) of toys with regard to their development in all parts of the world and their persistence to the present that is amazing. In Egypt, America, China, Japan and among the Arctic people, generally the same kinds of toys appeared. Differences depended on local customs and way of life because toys imitate their surrounding. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.

Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize(具有…的特征) inventions for adult use. The progress from the wheel to the cart to the automobile is a direct line of ways up. The progress from a rattle(拨浪鼓) used by a baby in 3,000 BC to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the time and subject to the limitations of available materials.

1. The reason why the toys most boys play with are different from those that girls play with is that______.

A. boys like to play with their fathers while girl with their mothers

B. they like challenging activities

C. most boys would like to follow their fathers' professions

D. their social roles are rigidly determined

2. One aspect of "the universality of toys" lies in the fact that________.

A. the basic characteristics of toys are the same all over the world

B. technological advances have greatly improved the durability of toys

C. the exploration of the universe has led to the creation of new kinds of toys

D. the improvement of craftsmanship in making toys depends on the efforts of universities

3. Regarded as a kind of art form, toys________.

A. reflect the pace of social progress

B. changes a lot as time goes by

C. are not characterized by technological progress

D. also appeal greatly to adults

4. The author uses the example of a rattle to show that________.

A. it often takes a long time to introduce new technology into toy-making

B. even the simplest toys can reflect the progress of technology

C. even a simple toy can mirror the artistic tastes of the time

D. in toy-making there is a continuity in the use of materials

People have been wondering why elephants do not develop cancer even though they have lifespans (寿命) that are similar to humans, jiving for around 50 to 70 years.

Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

According to the research, the extra copies of the gene improved the animal’s sensitivity to DNA damage, which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals,” the study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous (癌变的), large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. But across species, the risk of cancer does not show a connection with body mass.

This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto’s paradox (悖论)”. Biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant’s case, the making of TP53 is nature’s way of keeping this species alive.

The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place.

“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. “It’s up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people.”

1.Why are elephants unlikely to develop cancer?

A.They have a rather large body size.

B.Their genes suffer no DNA damage.

C.Certain genes in their body kill existing tumors.

D.They carry many genes to prevent tumors developing.

2.According to the passage, what has been a risk in the evolution of large animals?

A.Deadly tumors. B.The huge body mass.

C.Cells killing themselves. D.Sensitivity to DNA damage.

3.What does the underlined part “This phenomenon” in Paragraph 5 probably refer to?

A.Larger animals have protection from TP53.

B.The risk of cancer is not related to body size.

C.Larger animals suffer the same risk of cancer as smaller ones.

D.The larger animals are, the bigger risk of cancer they will have.

4.What can be concluded from the passage?

A.Depending on nature is surely enough to fight against cancer.

B.The TP53 genes have proved useful in stopping cancer in people.

C.Humans are expected to prevent cancer with the making of TP53.

D.The extra copies of elephants, genes are used to cure cancer patients.

Thousands of villages in the developing world have no telephones. They have no money to build telephone systems. A new kind of technology may help change this situation. I t reduces the cost of building and using telephone systems.

Traditional systems use wires to carry electrical signals from one telephone to another. The wires often cost much more than telephones. The new system is based on radio communication. Each telephone sends and receives signals through the air, but not through the wires. This reduces the cost greatly. The radio telephone gets their power from the sun.

Each is connected to a solar equipment that changes the sun’s energy into electricity. A battery stores the electricity until someone needs to make or receive a call. The telephone turns off by itself if the level of power in the battery falls too low. This prevents damage to the system. Each radio telephone is connected to a computer microprocessor. It rewards how many calls are sent and received. It controls the power supply.

The technology needs more study, but its new use of radio equipment sun power and computers may help start telephone ringing in the other parts of the world.

68. The radio telephone gets their power from_____.

A. the sun 　　B. electricity 　　C. battery 　　D. a special equipment

69. Each telephone is connected to_____.

A. a solar equipment 　　　　　B. a radio machine

C. a computer microprocessor 　　D. Both A and C

70. From the passage we can infer that_____.

A. the new telephone system costs less than before

B. we can not use the radio as before

C. the new telephone system will take the place of the old one

D. it will be much easier to radio from now on

71. The main idea of the passage is_____.

A. a simple telephone system has been invented and costs less money

B. thousands of villages will use the new telephone system very soon

C. traditional telephone system will become useless

D. the new system will be too good to use
